Fluid Mechanics MCQ with Answers

111) Which of the following manometer has highest sensitivity

Answer is:

micro-manometer with water

112) In order to increase sensitivity of U-tube manometer, one leg is usually inclined by angle 9. Sensitivity of inclined tube to sensitivity of U-tube is equal to

Answer is:

sin 9

113) Working principle of dead weight pressure gauge tester is based on

Answer is:

Pascal′s law

Explanation:

According to Pascal’s law, the intensity of pressure at any point in a fluid at rest is same in all directions.
Working principle of dead weight pressure gauge tester is based on Pascal's law.
